Shafted Grit Classifier vs Shaftless Grit Classifier
Typically in shafted systems a layer of grit forms between the OD of the spiral and the ID of the screw conveyor trough, where only minimal movement of grit occurs. For larger plants, or plants where the grit classifier has long hours of operation …

SPIRAL CLASSIFIERS
Spiral/Screw Classifier Speed. The speed of the conveyor should be just sufficient to handle the sands to be removed. The slower the speed the less the agitation in the pool and the finer the overflow. The lower the speed the longer the life of the classifier and all wearing parts.

Rake Classifier
rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up the incline to the discharge.
